BOILER-CLEANER.

Specification of Letters Patent.

Application filed January 25, 1912.

Patented Apr. 2, 1912. Serial No. 673,353.

To all whom it may concern:

Be it known that I, EDWARD S. Cum a citizen of the United States,residing at Phoenixville, in the county of Chester and State ofPennsylvania, have invented certain new and useful Improvements inBoiler-Cleaners, of which the following is a specification.

My invention relates to improvements in boiler cleaners, the object ofthe invention being to provide a tool which is adapted to cut washersfrom the inner face of boiler structures, and which may be projectedthrough an opening of less diameter than the length of the cutter bar bypositioning the cutter bar at an angle to its support.

A further object is to provide an improved construction of cutter barand cutters which may be reversed in the cutter bar so as to lengthenthe life of the cutter without sharpening.

With these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a View in side elevationillustrating in full lines the cutter bar in normal position, and indotted lines in position to be inserted through a boiler opening. Fig.2, is a view at right angles to Fig. 1, and Fig. 3, is a plan View ofFig. 1.

1, represents a fork or support having an angular integral shank 2 to beconnected with any suitable mechanism for turning the same. The freeends of fork 1 are made with registering openings 3 for theaccommodation of a bolt 4. This bolt 4 has a head 5 at one end, and issecured by a nut (5 at its other end, and between the members of thefork is positioned through a central opening 7 therein a cutter bar 8,so that while the cutter bar is secured to the fork, it is permitted apivotal movement therein so as to position it at any desired angle withrelation to the fork.

The cutter bar 8 is of general rectangular form in cross section, and atits ends is recessed as shown at 9 to expose the sides of the ends ofthe cutters 10. These cutters 10 are secured in longitudinal grooves 11in the inner face of the cutter bar by means of set screws 12, which arescrewed through.

threaded openings 13 in thebar, andjammed against the side faces of thecutters. Each cutter- 10 comprises a bar of steel having its inner andouter faces beveled forming sharp cutting edges 11. By beveling bothfaces of the cutter, the latter may be reversed in the holder, so thattwo cutting edges are provided on each cutter, and when one becomesdull, the other may be brought into play by reversing the cutter.

By reference particularly to Fig. 3, it will be noted that the ends ofthe cutter bar and the inner walls of the recesses 9 are curvedconcentrically with the center of the bar, and as this bar is adapted tobe turned with its center as an axis, and its cutters against a washeror uneven surface on the inside of a boiler, said cutters will move in acircle and cleanly cut the seat and the washer therefrom. WVhen it isdesired to insert the cutter, the bar is positioned at an angle as shownin dotted lines in Fig. 1, when it may be projected through an openingof a diameter less than the length of the cutter bar. When once throughthe opening, the cutter bar is positioned at right angles to fork 1, andthen moved backwardly until its cutters l0 engage the washer. A turningmovement imparted to the fork will cause the cutters to clean the washer01' other foreign matter from the surface of the boiler.

Various slight changes might be made in the general form andarrangements of parts described without departing from my invention, andhence I do not limit myself to the precise details set fort-h, butconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A device of the character described, comprising a support adapted tobe connected to means for transmitting a rotary motion thereto, a barpivoted between its ends to said support, said bar having grooves in itsinner face at its ends, and cuttcrs secured in said grooves,substantially as described.

2. A device of the character described, comprising a support adapted tobe connected to means for transmitting a rotary motion thereto, a barpivoted between its ends to said support, said bar having grooves in itsinner face at its ends, cutters secured in said grooves, said bar beingrecessed at its ends, and said cutters at their outer ends projectinginto the recesses in the bar, substantially as described.

3. A device of the character described, comprising a fork, a bar, saidbar and said fork having registering openings, the opening in the barbeing in the center thereof, a bolt projecting through said openings, anut on one end of said bolt, said bar having recesses in its inner faceat its ends, and longitudinal grooves communicating with said recesses,cutters located in said grooves, and projecting into the recesses, andmeans in the bar for securing the cutters in the grooves, substantiallyas described.

4:. A device of the character described, comprising a fork, a bar, saidbar and said fork having registering openings, the opening in the barbeing in the center thereof, a bolt projecting through said openings, anut on one end of said bolt, said bar having recesses in its inner faceat its ends, and longitudinal grooves communicating with said recesses,cutters located in said grooves, and projecting into the recesses, andmeans in the bar for securing the cutters in the grooves, said cuttershaving their outer and inner faces beveled, substantially as de scribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
